Hi, I'm having the weirdest problem trying to jailbreak my friend and his brother's two 8gb iphone 3g's (3g, not 3g). Nearly every time I try, it hangs up with the blackra1n program saying "running" and the phone showing the connect to itunes screen. One time after restarting, one of them did jailbreak, but after installing cydia from blackra1n, it crashed a few seconds after opening, every single time. I also tried it on another computer, still same problem. Both computers are windows xp, logged on as admin accounts. Any suggestions?
